Gamegossip are reporting on an article in Time magazine and also on the Time magazine website in which Microsoft CEO Bill Gates confirms that Halo 3 is in development for the Xbox 360.
The one thing that stands out however, is that the game is not due to be launched with the next-gen console, rather used as a time-bomb set to go off with the release of the Ps3.
“It seems that the next Halo won't be an Xbox 360 launch title, but a title set to launch as a disruption to the PlayStation 3 launch, arriving as a second wave of titles during spring of 2006.”
